[Pw_forum] Ph.x code help

[Samin, Adib J.]

Thank you so much for all your help. I was finally able to run the code by reducing the number of processors being used.
I still have one question however. The si.dynG file I am creating seems to be a blank file. Is that correct? 
I am currently attempting to run dynmat.x to diagonalize the matrix but I am concerned because I don't see the matrix.

Thanks,

Adib Samin
